IPERFORATING-MACHINE.

Specification of Letters Patent.

Original application led July 6, 1905, Serial No. 268,494. Divided and this application :tiled December 1, 1909. Serial No. 530,793.

To all whom it may concern Be it known that I, LOUIS M. Po'rrs, a citizen of the United States, residing at Baltimore city, in the State of Maryland, have invented certain new and useful Improvements 'f in Performing-Machines, of which Vthe following is a specification. v

The primary 'object of this invention is A further object of the said invention is the production of a machine of the above character which, in addition to producing code impressions of the kind above described, also impresses on the same sheet therewith printed characters corresponding to the respective code impressions, and arranged in similar line to line formation.

Other objects of the said :invention will more -fully appear from the following de' tail description of my said invention.

Themachine forming the'subect of the present application was origina ly'shown, escribed, and claimed in an applicationv for improvements in automatic telegra hs and the like filed by me July 6, 1905, er. No. 268,494, on which was granted December 7 1909, Patent No. 942,844, and of which application the present one isa division.

In order to more fully describe my said invention reference will be had to the accompanying drawings wherein,

Flgure 1, represents one form of controlling device prepared with my improved machine; Fig. 2, a central vertical section partly in elevation of one form of the said machine; Fig. 3, atop plan view of the same, showing the electric circuits whereby 1t is' operated; Fig. 4, an enlarged development of the type-wheel of said machine; Fig. 5,

' Patent No.

an enlarged fragmentary vertical section of said typewheel and the punching device operated thereby; Fig. 6, -a top plan view o f the same, and Fig. 7, an enlarged sectional view of the auxiliary punching device forperforating the controlling form at the commencement of each line.

In the following description it will be assumed that the prepared form is intended to controlan automatic telegra h transmitter. vI shall rst describe one o these forms and then describe the machine for preparing them.

. The form, as shown in Fig. 1, consists of a sheet or page 'of paper or other suitable material having thereon a plurality of impressions arranged in accordance with a pre-selected code, and a printed or typewritten' character corresponding to each code impression or combmation of impressions representing such character. These code impressions may consist of perforations, embossments or any other forms of impression which will accomplish substantially the same result. The message is impressed on the blank in aseries of horizontal lines as in .ordinary writing, and when printed characters are used, the code impressions are arranged in a verticalline either directly above or below the rinted character represented thereb L In t e specific form herein shown the co e impressions are in the form of Small perforations 1, and two of such fperforations are combined, according to a co v described, to forma letter of the alphabet, numeral, or other symbol. The code herein described is substantiall. that of the Rowland system',z described 1n one form in the granted November 11, 1902, wherin eleven circuits of a keyboard are comblned twoand-two to effect a large number of comb1- nations, each of which effects the transmission of a diiierent signal. For the purpose of explaining how the perforations are arranged on the sending form accordin to this code, let thefoarm (Fig. 1) be divlded Patented Feb. `27, y1912.-

e now to be by a series of imaginary horizontal arallel lines of four groups, indicated by t e dotted lines lettered a, b, c, d, e, f, g, h, z', and lc, and let each of these oups of imaginary lines correspond toa l1ne of matter to be transmitted. Then for each character in.

yao

` springs.

said line of matter there willl be two perforations located upon two such horizontal lines. For example, the code arrangement of perforations to produce the letter A- consists of a perforation on the horizontal line b an`d a perforation located directly thereunder on the horizontal line f code arrangement for the letter J consists of two perforations located one above the other on the @and z' lines, respectively, and so on. vEach vertical line of perforations forming a combination is spaced a suitable distance horizontally from the next adjacent combination.

At the same time that the form is per forated, the character or symbol representin the combination of perforations may be printed or typewritten thereon, preferably .directly above or beneath the code perforations. In the specimen illustrated in Fig. 1, these printed characters are directly beneath the code perforations. In this way the message may be easily read and mistakes readily detected before transmission.

The form shown is provided with a series of auxiliary perforations 2, along one of its edges, preferably opposite the commence. ment of each line of printed mat-ter. rlFhese perforations, register with l retaining devices on the transmitting apparatus for imparting motion -to the form, and act also as a means for accurately placing the forms in the transmitter each time in the proper position. A form ofthe machine for preparing these controlling devices is shown most clearly in Figs. 2 to 7 The spacing, lining, inking or ribbon mechanisms of this machine may be substantially the same as shown in the Patents Nos. 290,419 or 501,504, to J. B. Hammond, or of otherV forms,

such parts being omitted from the drawings'as unnecessary to a full understanding ofmy present invention.

In the machine illustrated, 3 represents..

the paper carrying carriage, having the paper holding rollers 4, 5 journaled l in the 'en-d brackets 6, 7, 8, a series of vertically movable stop pins arranged in the arc of a circle and supported by stationary frames 9 and l0 through which they pass. Each of v,these pins-is provided with a shoulder or lug 11 arranged to rest on'the lower frame 10, and above this-lug, a spiral spring -12 bearing at one end on such lu and at its upper end-against the lower ace of the frame 9. The pins 8 are therefore normally forced downward under the tension of said Each lpin 8"'is located directly above a pivoted key lever 13, in such man- .ner that by the depression of a key the stop pin corresponding thereto will be raised vertically, as `in, the Hammond machine above referred to.

The type-'wheel 14 is-mounted fast upon The from as at 17, a metal arm 18, the free end of which is arranged to pass over the top of the frame 9 over the upper ends of the stop pins. Rotary motion is imparted to the type-wheel through its spindle by means of two electromagnets or solenoids 19 and 20, the armatures ormovable cores 21 and 22 of which are securedeach to one end of two horizontally slidable rods 23, 24, made fast at their inner ends to a rack 25 which engages a pinion 26 mounted fast on the type-wheel spindle. The arm 18 is returned to itsinit-ial position by springs 23, 24 upon the rods 23, 24, said springs being accurately balanced against each other byl means of the adjusting nuts 23" and 24 'Ihe type-wheel is provided with a typeflange 27, and an upwardly extending flange or cylindrical portion 28 of smaller diameter than the type-flange. On the surface of this portion 28 is formed a plurality of small cams 29, arranged as shownmost clearly in the development of the typewheel, Fig. 4. "Ihese cams are arranged in combinations of two in a vertical line above each character on t-he type-wheel and lie in eleven horizontal rows, Ajust as in the'case to the frame of the machine ablock 30, hav

ing therein a vertical row of eleven chambers (see Fig. 5;), each. of said chambers opening through one side of the block by apertures 32 of smaller diameter than the chambers. In `each of these chambers is mounted a pin 33 having a shoulder or fixed collar 34 thereon arranged to engage one end of the chamber under'the `tensionof a coil spring 35 onthe pin. .One end of each of these pins extends through the. block 30 into close proximity to the surface of the cam portion of the typefwheel, while the other end extends into a bushing 36 in the other end ofthe chamber. These pins are so arranged and spaced that one will register with, or be in line with, each horizontal row of cams on the type-wheel, so that as each combination of cams in a vertical line comes in front of the vertical row of pins, a different combination of two such pins will be engaged by said cams and moved laterally against the tension of their springs 35, and caused to project (as shown in Fig. 5) beyond the face of the block 30. Located directly in front of this block 30, and

vertically elongated block having a verticali row of horizontal openings 38 therethrough, each of which is located exactly in line with a correspondingpin 33. Thev openings 38 ture vforward is adapted to bring a contactl 49 in electrical connection with the frame of 1 are of substantially thelsame -shape as the cross-section of said pins, thoughv -slight-ly larger in diameter, to receive them. On'a the lower end of the block37 is the type platen 39 adapted to be4 arranged in line with the type-flange; Y The block 37 is carried by tworods 40, which pass loosely through the magnet yoke 41 and rear cross pieces 42 of a; supporting bracket 43 made fast toa rigid upright 44. Theserods 40 carry at their ends opposite said block 37, an armature 45 which' lies in front of the poles of two electromagnets 46 made fast at their outer ends to a'prefera'bly nonmagnetic supporting bracket 43, as shown most clearly in Fig. 3.- These magnets are arranged when excited to vattract the armature 45 against the tension of springs 47 carried on the rods 40, and to thus send the f the carr1age reaches the end of its travel, the

block'37 forward. This op'eration causes the platen 39 to send the blanks (see Fig. 5) against the type. At the same time, the blanks 48 will be s ent by the block 37 against the combination of pins at that instant sent forward by the cams. The force of the block 37 is sufficient Ito drive said pins through the aper into the openings 38, thus perforatin the same in the desired combinations. he movement of the armathe machine, into engagement with a stationary insulated contact 50.

Arranged beneath the key levers 13 are two insulated conductors 51 and 52, the lati ter of which isarr'anged to be brought into electrical connection with all ofthe key levers on the right of the insulation 53, when said levers are depressed as in operatiom Iand the other of sald conductors is arranged 'to be similarly brought -into electrical con'- '50'l nection with the 'key levers on the left of said insulation, each of said key levers being, for this purpose, provided'with a small contact spring 54, though this contact spring may be dispensed with and the key levers made to engage the conductors 51 and .52,direct.

In addition to the above described punch- A ing arrangement, I provide an auxiliary punching device arranged' to perforate the.

telegraph form once near one edge as shown at 2 in Fig. 1, at the commencement of everyF line. This auxiliary punching device operates automatically' and consists` of two punching members 55 and 56 mounted rigidly -near one end of the carriage and-sep'aarm made fast as at 57 to the end frame 6 of the carriage. This member is provided, as shown most clearly in Fig. 7, with a chamber 58 in which is located a punching pin 59 havli-ng'a collar 60 fast thereon adapted tQ-e'n'- ga'ge the Awalls of said chamber. Thisl pin eXtends into an opening 61 through the i front of the block, of smaller diameter than the chamber 58.l Surrounding the pin 59 and between the collar andthe front wall @of the chamber 58 is a spiral spring -62 which is held under tension by the bushing 63 screwed into the chamber on the otherv side of the collar 60, the pin extending' through and out beyondj said bushingas shown. Pivoted between two'l-ugs 64 on the gmember 55, is a lever 65 having an arm 66 2 adapted to engage the end of the pin 59. A

larger arm 67 provided with a lug or pin 68 ,is arranged to engage a stop at a certain point of the rcarriage travel. This stop is shown in the present case as'an adjustable 4gscrew 6,9 carried by the lug 70 on the frame 43. This stop 69 is so located that when pin 68 will engage the head ofsaid screw 69 and cause the lever to send the peforating pin 59 forward.. Located exactly in line.

with the pin 59 is an opening 71 in the member 56 arranged to receive said pin ywhen Qsent forward as described.v (See Fig. 7). `=This member 56 may be made fast to the carriage in anydesiredway, but must be `held at all times in accurate alinemcnt with the member 55.

lnected to and Vdisconnected from a source of current supply indicated by the supply mains A and B, through the medium of Ithree' relays 72, 73 and 74, the electric circuits of'which may be readily traced fromthe following description of the operation.

ofthe machine: Let A land B represent respectively the positive and negative wires of a direct lcurrent circuit 'of a-proper voltage, vand let 13 represent any of the plurality fof keys depressed to print a letter or otherv Q'character. Upon the depression of this key gto the proper extent, an electric circuit will -be completed which may be traced .as folf lows: from the positive wire A through wire 75, coil 76 of relay 74, wire 77, cont-act strip 52, key lever. Contact 54, key lever 13,

pin 8, frame of the machine and thence'byl wire 78 back to the negative main B. The circuit thus lcompleted causes the vtongue of relay 74 to be sent against its forward contact 79, and this completes a second circuit which may be traced as follows: from positive main A to wire 80, coil of magnet 20, 'wire 81, relay contact 79, tongue of relay 74,

wire 82 and negative-main B. The circuit'v The electromagnets 19, 20 and 46 are con-l roo feb

thus completed causes current to Aenergize the magnet 20 which draws in its core 22, thereby rotating the type-wheel and arm 18.

This arm 18 stops the type-wheel in the proper place by engaging the pin 8 sent upward into its' path by the operation of key lever 13, and when the arm 18 thus' engages a pin 8 another electric circuit is completed which may be traced as follows: from the positive main A to wire 83, coil 84 of relay 72, wire 85 to insulated arm 18, pin 8, frame of the machine back by wire 78 to the negative main B. This circuit sends current through the coil 84 of' relay 72, and causes that relay to send its tongue against its forward contact 86, and this completes a circuit through the coils of the magnets 46 which may be traced as follows: from positive main A to wire 83, tongue of relay 72, contact 86, coils of magnets 46, wire 87 back tothe negative main B. The magnets 46 thus become energized, attract their armature 45, and send the combined punch member and platen 37 forward thus simultaneously punching the properl combination of code perforations in the-blankand printing the character corresponding thereto.` This movement of the armature causes the movable insulated contact 49 (see Fig. 2) to be brought into engagement with the fixed contactv 50 in electrical connection with the frame of the machine, thus completing a circuit which will restore all of the relay tongues to theirV initial positions and break the circuits through the operating magnets.'

This restoring circuit may be traced as follows: from the positive main A' to wire 88, coil 89 of relay 74, wire 90, coil 9l"of relay 73, wire. 92, coil 93 of relay :72, insulated bracket 50 carrying contact 50, contacts 50 and 49 to the frame ofthe machine, and thence by wire 78 back to thenegat-ive main B.r Current through this circuit sends the tongues of all of the relays against their back stop contacts thus breaking the circuits established through the magnets 20 and 46, nrestoring the parts to their initial positions. The armatures 21 and 22 andthe type-wheel are returned by the springs 23 and' 24. This is the complete operation Vfor printing a character and perforating the I blank or form when any of the key levers on the right of the insulation 53 (Fig. separating the contact strips 51y and 52 are operated. The operation for the keys on the left of said insulation is exactly'the same,` except in the `latter case the keyo levers make contact with the strip 51 instead of strip 52; the relay 73 takes the place of the relay 74, and the magnet 19 the place of the mag- Ilet- 20.

When the end of a line is reached, the pin 68 on the lever'y arm 67 'of the auxiliary punching device engages the stop 69, being sent thereagainst by the force of the carriage in its travel, and this causes the pin 59 to punch a hole in =the form corresponding to a hole 2, in Fig. 1. K
